I did a stupid thing and tried meth with a buddy of mine. I freaked out after slamming the med because of how it made me feel. My concern in that for two days after doing the slam this past Saturday I had really bad head pressure. I drank plenty of fluids, tried get rid of the pressure, but had a temperature of 99.2 and occasional rapid heartbeat. BP normal and pulse no higher than 101, but after I finally came off the high I had a red area on the upper back of my neck and lower back of my head and felt tight and now has turned a brownish color and the skin is flaking. I keep getting head pressure in the back of my head and upper neck and it goes to my ears. My ears then feel plugged and I get tingly sensations on the back of my head and sometimes my ears throb slightly. When I get the pressure to the back of my head that area feels heavy and numb. Could I have cause permanent blood vessel damage, etc?
